Veteran quarterback Kyle Orton announced Monday that he is retiring from the NFL.

Orton made 12 starts, going 7-5, for the Buffalo Bills after joining the team a month into the season and replacing second-year quarterback EJ Manuel.

"I just have been going at it for 10 years and it's just a family decision and I've decided to get home and be a dad and call it a day," said Orton, who was drafted by the Chicago Bears in 2005 out of Purdue and also played for the Denver Broncos, Kansas City Chiefs and Dallas Cowboys.

Without the 32-year-old Orton, the Bills could be in the market for a quarterback in the offseason. Philadelphia Eagles quarterbacks Nick Foles and Mark Sanchez are scheduled to be unrestricted free agents and would likely intrigue the Bills. Buffalo could also have interest in veteran Jay Cutler, who had a down year with the Chicago Bears and has six years remaining on the $126 million deal he signed before the 2014 season.

Manuel might get a second look, but his inability to secure the starting job in two seasons since he was drafted in the first round of out Florida State will force general manager Doug Whaley to find suitable competition, at the very least.

Orton had 18 touchdowns and 10 interceptions for the Bills in 2014. He started 82 games in 10 NFL seasons.
